Abstract
A two-piece intake assembly such as a coaxial poppet valve includes a main poppet valve with a stem attached to a head and an auxiliary poppet valve movable on the inner valve. A guiding element on the outer valve is configured to receive the inner valve stem, and is connected to an outer valve head configured to mate with the inner valve head and form a seal. The assembly provides a first vent opening formed by the action of a rocker arm on the inner valve stem and a second opening formed by the pressure differential between the combustion chamber and the intake port.
Claims17
A coaxial poppet valve comprising:
- a main poppet valve having a valve stem and a disc;
- an auxiliary poppet valve having a disc configured to fit around the main poppet valve and form a seal between a port tube and a combustion chamber, wherein the auxiliary poppet valve is slidably attached to the main poppet valve stem;
- and
- an upper spring located between an auxiliary poppet valve guiding element and the disc of the main poppet valve and a lower spring located between the guiding element and a valve guide.
A method of increasing flow dimension in an internal combustion engine comprising;
- slidably attaching an auxiliary poppet valve to a valve stem of a main poppet valve such that a disc of the main poppet valve forms an air tight seal with a disc of the auxiliary poppet valve;
- placing the attached auxiliary poppet valve and main poppet valve between an intake port tube and a combustion chamber of an internal combustion engine;
- and
- placing an upper spring on a spring seat on an upper surface of an auxiliary poppet guiding member and placing a lower spring on a spring seat of a lower surface of the auxiliary poppet guiding member.
A two-piece intake valve assembly comprising:
- an inner valve having a stem attached to a head;
- an outer valve movable on the inner valve and having a guiding element configured to receive the inner valve stem, the guiding element connected to an outer valve head configured to mate with the inner valve head and form a seal;
- and
- a first spring located between the outer valve guiding element and the head of the inner valve and a second spring located between the outer valve guiding element and a valve guide.
